This is well known in LW, but I just want to add that Goertzel doesn't believe in the FAI research MIRI does and considers it meaningless daydreaming. He doesn't think a provably friendly AI is realistic and thinks a better approach is to pursue practical approaches to making the AI more friendly.
Well, if the summary is correct, he also thinks that a coin has consciousness, which is far worse than not endorsing MIRI research program and far more concerning about a person who works on AI.

I've never heard of this before, and have only watched 7 minutes so far, but I'd imagine many people here would be interested in this video.
